Abstract :
The control system plays a key role in the spaceborne radar altimeter, such as it should implement track function to provide the height from the satellite to the sea surface, the significant wave height (SWH) and the backscatter coefficient. In this paper, the design of the China spaceborne radar altimeter control system (RACS), which is one part of Multi-mode Microwave Remote Sensor (M3RS), is discussed in detail. RACS can realize the function of noise-bias measurement, inner calibration, return wave acquisition-track process, and data transfer. A new algorithm to implement the IF simulation signal is brought forward, and an IF simulator is developed to test RACS. RACS is also successfully tested in the airborne flight experiment.
